I don't get anything when I depress any of the holding tank buttons or the LP button at the one place panel.They just quit working. No lights come on. I looked for a triped breaker or fuse but do not see any that are abnormal. Any ideas?

If you have power in the rest of the coach so you're sure you havn't hit the battery disconnect switch, then I'd remove the one place panel and check the connections behind it to see if any are loose.

Download the following One Place Wiring Diagram for your rig and you will see the pinouts for the connector powering the display panel. Check the appropriate labeld pins for power and ground.

In the event that your panel should indeed be defective and not covered by warranty, consider replacing it with one of the digital display panels.

Thanks Joe-K for the info and link. I don't see any fuse on the wiring diagram. Surely it is fused someplace. Does someone know of an inline fuse or something? I'll be going down to Truman lake where I keep my RV this weekend.
Thanks,
Charlie

Joe-k
I check at the panel and I have both +12v and ground entering the circuit board. Didn't see any loose connections. I suspect the circuit board has a bad component however I see the ground is multipled from each tank on the drawing. I wonder if the ground is broken someplace. Problem is it is all in the wire harnasa going down the rail. Also I don't see the gray and Black water tank or sensors. Hard to get to. Any more ideas? Also do you have ording info for the circuit board you suggested.
Thanks,
Rigrunner

If you've measured and found both power and ground at the circuit board and still no lights at all on it, it sounds like a board problem. I would think that a problem with the sensors would show as inaccurate levels being displayed. It's been a while since I messed with my display panel as I use the See Level digital tank monitor system now.

Below is the link for a thread where I installed the digital system if you can't get yours and decide to upgrade the panel. Ours is installed in a Journey, but there's another guy on the forum who's installed his in a 35U like yours.
